Terms of Service

Tuda eSIM is sold and provided by TudaSim Limited, 42C, 69 Hollywood Road, Central, Hong Kong (“we”, “us”). Connectivity is delivered through our mobile network partners.

We sell prepaid mobile data plans delivered as an eSIM. Each plan has a data allowance, a validity period and a list of countries where it works, shown before you pay. Plans are for mobile data only; they do not include a phone number, calls or SMS unless stated otherwise.

You are responsible for checking, before you buy, that your device supports eSIM and is not locked to a carrier. See our device list or ask support if you are not sure.

Prices are shown in the currency displayed at checkout and include any applicable taxes unless stated otherwise. Payment is taken in full when you order. Payments are processed by our payment provider.

After payment we send the eSIM QR code and installation instructions by email, and show them in your account. The validity period starts when your device first connects to a supported network in a destination country, unless the plan says otherwise. Unused data does not carry over after the plan expires.

• An eSIM plan is non-refundable once it has been installed on a device or activated.
• If the eSIM cannot be installed or does not work because of a fault on our side or our network partners’ side, and our support cannot fix it, we will refund the plan in full.

Details are in our Refund Policy, which forms part of these Terms.

Plans are for personal use while travelling. You must not resell plans, use them for illegal purposes, send spam, run servers or automated traffic, or use them in ways that damage the network or other users. Unlimited plans may be subject to speed reduction after high usage, as described in the plan. We may suspend a plan that is used in breach of this section.

Coverage and speed depend on local networks, your device and your location. We do our best to provide reliable service but cannot guarantee uninterrupted coverage or a particular speed.

To the extent permitted by law, our total liability for any claim related to a plan is limited to the price you paid for that plan. We are not liable for indirect losses, such as missed bookings or lost profit. Nothing in these Terms limits liability that cannot be limited by law.

We may update these Terms. The version in force when you placed your order applies to that order.

These Terms are governed by the laws of the Hong Kong Special Administrative Region. Disputes are subject to the jurisdiction of the courts of Hong Kong, without affecting any mandatory consumer protection rights you have where you live.
